Description
本發明有關於一種具有內嵌式觸控感測器的顯示裝置及其製備方法,尤指一種具有內嵌式觸控感測器的有機發光二極體顯示裝置及其製備方法。The present invention relates to a display device with an embedded touch sensor and a manufacturing method thereof, in particular to an organic light emitting diode display device with an embedded touch sensor and a manufacturing method thereof.
觸控顯示面板的應用範圍越來越廣泛,更多電子產品增加了觸控顯示面板的功能,以提供使用者直接進行操作或下達指令的功能,也因此,觸控顯示面板的需求量不斷增加。The application range of touch display panels is becoming more and more extensive, and more and more electronic products have added the functions of touch display panels to provide users with the function of directly operating or issuing instructions. Therefore, the demand for touch display panels continues to increase .
現今奈米銀觸控技術皆屬外掛式方案(Out-cell),然而外掛式奈米銀觸控面板在系統模組的整合上,需再經過貼合程序,以將觸控面板黏貼於顯示器上,而多一道貼合程序,需增加重複移除保護膜或離型膜後塗佈黏著劑的步驟,製程相對繁複、耗時、且昂貴。除了會影響生產製造良率之外,模組化後之整體疊構厚度也會相對較厚,進而影響產品的彎折性。Today's silver nanometer touch technology is an out-cell solution. However, in the integration of system modules, the out-cell silver nanometer touch panel needs to go through a bonding process to stick the touch panel to the display. On the other hand, there is an additional lamination process, which requires repeated steps of removing the protective film or release film and then applying the adhesive. The process is relatively complicated, time-consuming, and expensive. In addition to affecting the production yield, the overall stack thickness after modularization will be relatively thick, which will affect the bendability of the product.
然而,奈米銀觸控面板的製備過程中包括了高溫烘烤的步驟,因此,若欲發展內嵌式的奈米銀觸控顯示面板,尤其當顯示面板為有機發光二極體顯示面板(OLED)時,奈米銀觸控面板的高溫製程可能造成OLED性能的損害。However, the preparation process of nano-silver touch panel includes a high-temperature baking step.

[面阻值及均勻性測試][Surface resistance and uniformity test]
本測試例係將奈米銀線以旋轉塗佈的方式,塗佈於一基板上,並將奈米銀線的塗佈製程溫度維持在100°C以下,調整其烘烤時間為0.5、1、2、5、10、20、30分鐘,並測試不同烘烤時間下所形成的奈米銀線層的面阻值以及均勻性。In this test example, silver nanowires are coated on a substrate by spin coating, and the coating process temperature of silver nanowires is maintained below 100°C, and the baking time is adjusted to 0.5, 1 , 2, 5, 10, 20, and 30 minutes, and tested the area resistance and uniformity of the silver nanowire layer formed under different baking times.
本測試例中的面阻值測試係使用非接觸式表面電阻量測系統,以渦電流感應的方式量測得到奈米銀線層的面阻值,其測試結果如表1所示。The areal resistance test in this test example uses a non-contact surface resistance measurement system to measure the areal resistance of the silver nano wire layer by means of eddy current induction. The test results are shown in Table 1.
本測試例中的均勻性的測試方法係取得樣品大小為15公分×15公分的區域內,等距劃分出九個量測點,並量測九個位置的面阻值,再藉由非均勻性公式以計算其非均勻性數值,公式如下: 非均勻性% = Rs max-Rs min/ 2 × Rs average The uniformity test method in this test example is to obtain nine measuring points equidistantly in an area with a sample size of 15 cm × 15 cm, and measure the surface resistance of the nine positions, and then use the non-uniform To calculate its non-uniformity value, the formula is as follows: Non-uniformity% = Rs max -Rs min / 2 × Rs average
而非均勻數值小於10%表示奈米銀線的具有優異的均勻性。A non-uniform value of less than 10% indicates excellent uniformity of the silver nanowires.
表1
由表1中所示的實驗數據可得知,比較例1至3的烘烤時間為0.5、1、及2分鐘所製備的導電薄膜的面阻值過高,其非均勻性數值過高,代表其均勻性不佳,而實施例1至4的烘烤時間延長至5、10、20、及30分鐘後,所製備的導電薄膜的面阻值及非均勻皆大幅降低,代表實施例1至4的導電薄膜具有優異的導電特性以及均勻性 。因此,在100°C以下的低溫的奈米銀線的塗佈製程中,需要有至少5分鐘以上的烘烤時間,可穩定地形成具有高均勻性以及低面阻值的奈米銀線導電薄膜。From the experimental data shown in Table 1, it can be known that the baking time of Comparative Examples 1 to 3 is 0.5, 1, and 2 minutes. The area resistance of the prepared conductive film is too high, and its non-uniformity value is too high. It represents that its uniformity is not good, and after the baking time of Examples 1 to 4 is extended to 5, 10, 20, and 30 minutes, the area resistance and non-uniformity of the prepared conductive film are all greatly reduced, representing that of Example 1. The conductive thin films of 4 to 4 have excellent conductive characteristics and uniformity. Therefore, in the low-temperature coating process of silver nanowires below 100°C, a baking time of at least 5 minutes is required to stably form conductive silver nanowires with high uniformity and low areal resistance. film.
